This plugin works with Gerrit projects that use Android or Chromium compatible OWNERS files. The OWNERS files specify owners, or active maintainers, of a project and its directories or files. Changes to those files or directories will need owner's review and approval before submission, with some exceptions.

OWNERS files syntax is described in syntax.md. Projects with OWNERS file should be configured with Prolog submit_rule or submit_filter, see config.md.

A Find Owners button is added to the Gerrit revision screen if a change needs owner approval. The button pops up a window that contains

• current reviewers and owners of changed files for users to select, and
• optionally changed files without required owner code review vote.

A REST API is added to get owners information of a change. The API is described in rest-api.md.
